1. Turn off the power supply. Using a 10Ω, 10 W resistor, connect both ends of power supply

capacitors (C701, C703 and C702, C704) in order to discharge the voltage.

2. Before turning the power supply on, after completion of repair, slowly apply the primary
voltage by using a power supply voltage controller to make sure that the consumed current at
50 Hz in NO SIGNAL mode should be shown below with respectto supply voltage 230/240 V.

Power supply voltage AC 230 V AC 240 V

Consumed current 50 Hz 70 ~ 250 mA

2 Protection Circuitry

TOP PREVIOUS NEXT

The protection circuitry may have operated if either of the following conditions is noticed:

No sound is heard when the power is switched ON.

Sound stops during a performance.

The functions of this circuitry is to prevent circuitry damage if, for example, the positive and negative
speaker connection wires are shorted, or if speaker system with an impedance less than the indicated
rated impedance of this unit are used.

If this occurs, follow the procedure outlined below.

1. Switch OFF the power.

2. Determine the cause of the problem and correct it.

3. Switch ON the power once again.

Note:

When the protection circuitry functions, the unit will not operate unless the power is first switched
OFF and then ON again.

Indicated voltage values are the standard values for the unit measured by the DC electronic circuit
tester (high-impedance) with the chassis taken as standard. Therefore, there may exist some errors in
the voltage values, depending on theinternal impedance of the DC circuit tester.

No mark

Important safety notice:

Components identified by mark have special characteristics important for safety.

Furthermore, special parts which have purposes of fire-retardant (resistors), high-quality sound
(capacitors), low-noise (resistors), etc. are used.

When replacing any of components, be sure to use only manufacturer’s specified parts shown in the
parts list.

Caution!

IC and LSI are sensitive to static electricity.

Secondary trouble can be prevented by taking care during repair.

Cover the parts boxes made of plastics with aluminum foil.

Ground the soldering iron.

Put a conductive mat on the work table.

Do not touch the legs of IC or LSI with the fingers directly.
